Morning All, Opened the tent up this morning and noticed a few discolouration's on the LAPK's leaves so just wanted to put some pics up and get peoples thoughts.

Shes coming towards the end of her life now so im not too concerned about the paling as I think this is the plant pulling the last of the nitrogen out however its the brown/rusts sports that have appeared that I just want a 2nd opinion on. 

From what I can see it could be either Calcium or Potassium deficiency but would be really grateful for a 2nd opinion on that. Its Day 86 -43F today for her so shes probably only got maybe 3 weeks left so what would you do, just let her ride or up nutes in some way. Ive copied latest feeds below if that helps. Shes due a feed tomorrow so if I do need to add anything extra, would like to do it then.

Thanks all and as always any help greatly appreciated.

What lights out temp are we looking at Jedi? Looks like the purple genetics are being triggered by cold is my guess. I’ve got a Violet Kush going that’s doing the same thing.

@monkeydo could be the cold but would they not need to drop drastically, like in the region of 10-15 deg to cause such a deficiency, thats if it is cold related i mean.

Cool thanks for taking a look guys and for the replies. It drops to about 18C at lights out but that is about a 10-11C drop. It has been freezing here aswell, last cpl of days -2 and blanketed in snow.

Nothing to worry about then really, like I say i was expecting her to start paling now so im not worried about that. I'll just give her the normal planned feed tomorrow then.

Thanks again everyone.

Yo bro.. I think she’s just sensing autumn is ending and she’s ripening up for the end using what she has on board.. those are all lower leaves which hold mobile nutrients allowing the plant to reduce-distribute them as her needs and desires dictate ...

Either that or you’re fucked ! 

just kidding!

Don’t think all plants are meant to stay solid green all their lives, also some are harder to supply the exact correct ratios throughout of npk + macro nutrients, so maybe a touch short of something nutrition related but how much does that affect your harvest, probably not at all, or immeasurably so .. 

 Could be wrong of course but that’s where I’m at

@chillbert Hahaha yeah I agree with you man, I was cool with the leaves paling but I didnt know this was a purple strain to be honest but that would explain it as temps have been cold here last few days.
